Modeling and simulation of Cylindrical PET 2D using direct inversion method

Abstract

Our purpose is to model the imaging process in 2D PET imagery. More directly, considering a unit point source located at point Mn and emitting pairs of opposite twin photons in an isotropic way and a pair of non adjacent detectors (i, j) located on the detector ring, our objective is to determine the proportion of the flux emitted at point Mn which jointly hits the detector pair (i, j).
